I grabbed these as a lightly used demo unit for sale on Amazon. Total steal for $110, but I would've paid $150 for them.
I was looking for an upgrade to my SE215, and these are it. The bass is tighter and has better control, the midrange and treble are more detailed, and it doesn't get over-warm like the SE215. I actually prefer it to the SM3 personally; while its a hair behind in detail and the bass isn't quite as satisfyingly tight, it's about 95% the same sound, and doesn't get overly intimate or "weird" sounding like the SM3 did; I swear I spent so much time switching the cables around on my SM3, reading up on polarity, etc. because it just sounded WEIRD! Something about...

Cons: Sometimes a touch too warm and intimate, but never intrusively so

I've been listening to a sample unit of HRT's new flagship DAC, the Music Streamer HD, for about a month now, and have been comparing it pretty extensively to the microStreamer. I began my demo by listening to the HD as soon as I got it, and I loved the sound right off the bat, but unfortunately I had a few things come up in my life and didn’t get to use the HD much in the following weeks due to travel and general lack of time. I kept using the microStreamer, as it is literally attached to my laptop, and used it for essentially all of my listening over the next 2 weeks.
I noticed something, though, about the uS that I had not felt before: it seemed to be lacking a bit of bass,...

Cons: AWFUL DURABILITY AND CUSTOMER SERVICE, will hiss with most sources, distorts at medium-high volume, awkward plug, short cable

These were my favorite sounding universal IEMs, and my praise for their sound can be read throughout the most recent iteration of the SM3 appreciation thread, but I feel a strong need to let people know about the durability issues with Earsonics products, and the company's treatment of customers as a whole.
My first pair of SM3 V2s lasted about 3 months before half of the right shell came off while walking down the sidewalk. I pinched the IEM gently by the shell to pull it out of my ear, and it just came straight apart. I got in touch with Earsonics customer service, and shipped them to France for about $60 with the assurance that they would be repaired at no additional cost...

Cons: Treble lacks extension, fit not for everyone due to bulky connectors and so-so memory wire (not a problem with mic cable)

I will report back for a more in-depth review of the sound, but for now suffice to say that I love the SE215 and it is my go-to beater IEM when I'm not willing to risk my UM3X. It does bass and vocals exceptionally well, which are my two biggest desires from any headphone. Durability is unparalleled, especially for the price. I take these everywhere: workouts, running, beach, etc. and never feel like I have to worry for even a moment about anything going wrong. They are isolation monsters, too; they made great commuting companions when I took the train and bus to work. They are usually my first recommendation to non-audiophiles who are sick of crappy Skullcandies giving out after a...

Pros: Great timber, detailed and neutral mids, best separation of any IEM I've heard; very textured, well-imaged, three-dimensional sound

Cons: Soundstage not as big as TF10, SM3, etc. A bit dark and thick with stock cable

My setup for this review is Foobar2000 + WASAPI Event Out -> HRT MicroStreamer -> UM3X RC with Moon Audio Silver Dragon
I traded for the UM3X about two weeks ago and I haven't used another IEM since.
Currently listening to Classic Sinatra II in FLAC. Everything is well separated, to the point that it feels about as well-differentiated as my HD598 and DT770 in terms of instruments being presented distinctly from one another and not bleeding into each others' space; obviously soundstage size is nothing to speak of by comparison, and the UM3X is on the smaller side as far as triple drivers go, but I think that makes its ability to separate sounds amost even more...

Cons: Mine has a cubed right angle jack that doesn't work with my Nexus 4 case; want to reterminate with the ViaBlu when I get the cash

I got my Silver Dragon in a trade, and am really loving it. I will probably come back to do a more in-depth explanation of the differences I hear on my UM3X between the stock EPIC cable and the SD.
For now, suffice to say I am definitely impressed by the construction. The cable is thick and obviously sturdy, but also very flexible and soft. All of the strain reliefs and connecting points also feel strong and are flexible where they need to be. Despite the lack of memory wire, the cable tucks snugly behind my ears and doesn't give me any problems.
I do hear some changes in the sound that I cant just ignore. The bass feels lighter and tighter, and treble is much more...

Cons: Less bass than many look for, poor isolation, can be revealing of less than perfect recordings

Having recently reviewed the Charm 3, I've become more aware of the actual benefits of the earbud form factor; prior to the Charm 3, I had only ever heard iBuds and the new earpods. The Charm 3 introduced me to the very real spacial benefits of the earbud form factor, which, despite the popularity of IEMs, especialy multi-armature universals and customs among earphone-oriented audiophiles, seemingly deserves more attention, especially for the "soundstage-heads" among users of in-ears.
Sunrise claims that the Dragon 2 is their most technical earbud to date, so I figured I would put it through its paces with some classical piano and orchestral music. Beethoven's Moonlight...

My setup for this review: Foobar 2k WASAPI Output ->HiFiMeDIY Sabre DAC -> FiiO E11
As everyone knows, Apple has new "Ear Pods" that come packaged with their new products, and seem to be pretty popular, coming from someone who sells iPhones in wireless retail. They are a bit of a hybrid IEM-Earbud style, which I find pretty cool, but the sound signature is decidedly oriented to the masses, and while they are a welcome improvement over the old iBuds in just about every way, they also pursue a decidedly thick and bassy signature, which, while not unappreciable, will not satisfy everyone, especially here at Head-Fi.
Enter the Sunrise Audio Charm 3.

Cons: Not the fastest or most crisp sound, bass could be a smidge tighter; Sennheiser house sound isn't for everyone

My chain: FLAC/320kbps MP3 -> Foobar 2k WASAPI Output-> HiFiMeDIY Sabre DAC -> E11 -> HD598
My first taste of the Sennheiser house sound came in the form of the HD439, which I purchased while looking for a balanced all-rounder for casual listening on the go and in coffee shops while writing. I enjoyed the signature, so when it came time to look for an open headphone, the first place I looked was Sennheiser.
I usually favor phones that have slightly elevated bass and are a bit darker, and after reading reviews saying that the HD5x8 series shared the same drivers, I decided that the HD558 was likely the best way to go, assuming it wouldn't sacrifice...

Pros: Great bass, fun sound, expandable to 5.1, sound awesome right out of the iMac

Cons: Bass can be obtrusive

Got these babies open box from ebay for a hundred smackers, can't beat it.
The bass is AWESOME. Notes go waaaay down low, not the tightest I've heard from subwoofers but still sounds great with plenty of subbass grunt to make anything with lots of bass sound .
Overall the sound is bass-slanted as one would expect from a 2.1 system with a sub this size, but the mids and treble do not suffer. Treble seems to extend plenty far enough and the mids are only occasionally overshadowed by the bass; the main low-end emphasis seems to come in mostly below 200hz so there isn't tons of midbass bleed, more just occasionally excessive boom.
I think these...
